Chris King Gen 4 rear hub update is a much appreciated one for those who love versatility in their drivetrain setups. The R45, R45D, and Boost CL/6 Bolt rear hubs have all received the Gen 4 treatment, bringing new features while retaining the trusted main hubshells, bearings, and RingDrive components. If your hub is running smoothly, there's no rush to upgrade, but if you're in the market for new hubs or internals, Gen 4 is a welcome innovation.

If you have a previous model hub and want to upgrade, conversion kits are available. These kits include the axle, adjusting clamp, axle ends, and driver with bearings – everything you need to update your hub. Drivers are also available if you want to swap your driver/cassette type.

For those with a Twin Bearing Boost CL or 6 Bolt hub wanting to swap the driver/cassette type, Twin Bearing drivers are still available at a lower cost than upgrading to Gen 4. Check out the options here:Twin Bearing Boost CL or 6 Bolt Hub
